Sr. Software Engineer

The company

Parq delivers the world's fastest, highest-quality Environmental Product Declarations (EPDs), transforming the complex environmental reporting ecosystem. Through cutting-edge AI and large language models, we empower manufacturers to reduce their environmental impact and create a sustainable future.

Our founder created Parq after experiencing the EPD process firsthand. Frustrated by its lengthy duration, exorbitant consulting fees, and complex stakeholder requirements, he witnessed how manufacturing companies—the very builders of our world—were being underserved. This inspired him to revolutionize the process.

The opportunity is massive: in 2024, over $400 billion in construction projects required environmental product declarations. Since our founding in 2023, Parq has gained significant traction with ten recurring customers—and over 20 pilots and early-stage engagements.

We blend in-person collaboration at our Austin, TX office with flexible 3–5 day work weeks, nurturing a culture where freedom, gratitude, and integrity drive meaningful impact.
